The Guirado Estate offers Certificates of Authenticity for paintings by Juan Antonio Guirado. To obtain a certificate, please provide proof of ownership purchase details, clear photos, and measurements of the painting. Without proof of provenance, the painting will not be recognized as a work by Guirado. We also work with select secondary market dealers and can notify you of sales opportunities. If you are an auction house, please contact us to certify the authenticity of any Guirado paintings for sale. We do not recognize any paintings that have not been authenticated by the estate.
